Improvement in dumping-wagons



NTTED STATES HAMILTON BAILEY, OF HARRISBURG, PENNSYLVANIA.

PATENT @Cirri/GE? l IMPROVEMENT IN DuMPiN'G-WAGONS.

Specification forming p, rt of Letters Patent No. 209,745, dated November 12,1878; application filed n August 22, 1878.

To all whom it may concern:

Be it known that I, HAMILTON BAILEY, of the city of Harrisburg, county of Dauphin, and State of Pennsylvania, have invented a new and useful Improvement in Dumping-Vehicles, which improvement is fully set forth in the following specification and accompanying drawing, in whichp Figure l is a side elevationl of my dumpingvehicle with the near wheels of the vehicle removed,'and showing', by indicated lines, the Wagon-bed adjusted and in position for discharging its contents. Fig. 2 'represents a rear-end view of my dumping-vehicle bed and the devices employed for raising said end thereof. Fig. 3 represents one of the slotted hinge-plates at rear end of the wagon-bed carriers.

My present application-is an improvement on my patent on dumping-wagons, dated November 27 1877, and numbered 197,447. I employ the devices securedby said patent onthe front end of the bed-carriers for elevating said end of the wagon-bed, substantially as and for the purposes described in said patent.

The object of my present improvement is to provide the rear end of a dumping-vehicle bed with a hoist apparatus, whereby it may also be elevated toattain a better inclination for chutes across pavements for the discharge of coal into cellar-openings, the devices for hoisting the said rear end being mainly a modification of those employed on said front end, certain plates and ratchet appliances being eniployed in a novel manner.

My invention therefore consists, rst, in providing` the rear ends of dumping-wagon bed-carriers with slotted hinge-plates, whereby the hinge articulation may be adjusted vertically to attain sufficient elevation at said end for discharge-chutes to have proper inclination; second, in a peculiar combination and arrangement of hoisting devices located at the rear end of the wagonbed, under and on the sides thereof, in such manner that they may not obstruct the place for carrying the chutes thereunder, and operated by ratchet, gears, le-

` ver, and pawls, as described hereinafter.

I mount my dumping-vehicle bed J on truck -rails or carriers G G, which are supported in any approved manner upon a springvehicle,

My patent device for hoisting the front end of wagon-bed is shown at A b B C T.

My present improvements are the plates V,

Fig. 3, and the application thereto of wheels Al F, lever D, pawls K and X, shaft Z, which .is also connected with the hinged props N l and N? by means of chains a a, a' a. Each of said hin ge-plates V, Fig. 3, is made with bearing L for shaft Z, by which wheelv Al -is supported, with holes 1 2, through which it is bolted to the outside of rail G at its rear end with slot H, described with radius equal to length of rail G, through which, by stud O on bed-timber M, the bed may be hinged thereto at various elevations, according to adjustment of the parts hereinafter described. Said plates serve as guides vto prevent lateral displacement on the rails G Gr, and also hold the bed to place thereon longitudinally.

The hinged props N1 N2 are attached to the under side of wagon-bed aside from the middle thereof, to afford a space, Y, between them for the attachment and operation of chutes, which are usually carried on guides under the middle of said bed. Said props N1 N2 are connected at their forked pendulous ends with shaft Z by chains a a a. a', which are wound upon the shaft when the bed is hoisted, as shown in Fig. 2, said shaft being revolved by wheel A', which is driven by pinion Q on ratchet-wheel F, and the latter is rotated by lever D, pivoted to the stud which supports said wheel F, which the lever enga-ges by means of the pawl K, loosely pivoted thereto. A pawl, X, holds Wheel A' when lever D is not engaged, or is being vibrated back to take a rear step on the ratchet. After the bed J has been elevated, and it is desired to let it down, lever D is turned back without en gag ing its pawl K, and thus pawl X is disengaged by said lever-handle lifting the hook W, which is an extension of pawl X. The bed will then descend by its own gravity, unwindin g the chains a a a a from shaft Z.

When the wagon-bed is elevated in front and rear, as shown in Fig. 1, it is evident coal may be readily discharged therefrom by gravity, and a chute of any approved make may wheel A', lever D, ratchet-pinion F Q, pawls K and X, hook W, and props N1 N 2, connected with shaft Z by chains a a a a', and operating to adjust bed J at its rear end, substantially as set forth.

In testimony that I claim the foregoing as my invention I have hereunto set my hand and seal this 23d day of July, 187 S.
